Geography

Taichung City is located in the Taichung Basin along the main western coastal plain that stretches along the west coast from northern Taiwan almost to the southern tip. The city is located just north of 24° north and about 120.5° east longitude.

Taichung City borders Changhua County (彰化縣), Nantou County (南投縣), Hualien County (花蓮縣), Yilan County (宜蘭縣), Hsinchu County (新竹縣), Miaoli County (苗栗縣).

The Central Mountain Range lies just to the east of the city. Lower, rolling hills run to the north leading to Miaoli County. Flat coastal plains dominate the landscape to the south leading to Changhua County and the Taiwan Strait to the west.

Taichung has a warm humid subtropical climate (Köppen Cwa), with an average annual temperature of 23.0 °C (73.4 °F), and average annual rainfall of just above 1,700 millimetres (67 in). The average humidity is 80%. Taichung has a milder climate than other major cities in Taiwan. Due to the protection provided by the Central Mountain Range to the east and the Miaoli hills to the north, Taichung is rarely severely affected by typhoons. However, occasional typhoons emerging from the South China Sea can pose a threat to the city as evidenced by Typhoon Wayne in 1986, which struck the west coast of Taiwan near Taichung.
